The plot itself revolves around the discovery of Rapture by an unknown man, after his plane crashed in the middle of the Ocean. Controlled by the player, he will uncover Rapture's dark past, by listening to the audio-logs of its inhabitants and by facing Andrew Ryan's objectivist monstrosities. In the end, his quest will decide the fate of Rapture, according to the moral choices of the player. And though they are binary, if they're taken seriously, they can add a level of dramatic impact to the plot, making it much more meaningful. The narrative tends to move slowly and tries to establish certain moods, allowing the player to immerse in the chaotic nature of Rapture, while at the same time, learning about its convoluted history. Curiously, few cut-scenes are used, which ends up being both a blessing and a curse. On one side, you aren't obliged to sit through important plot details, but on the other side, much of the dramatic potential of the plot feels wasted.
What manages to counterweight the absence of cut-scenes, is the sheer amount of detail and information that lies hidden in the art and music of the game. Posters, sculptures, flyer's, songs, all have something to say about the world of Rapture, and whether you want to or not, you'll apprehend a lot of information that might be otherwise hard to convey. Of course, this wouldn't be that interesting if the Art Design or Music weren't as good as they are. The fact is that "Bioshock", besides featuring one of the best narratives to grace a game, also features one of the best art designs ever to appear in one. The virtuous art deco transforms every corridor, wall and painting into marvelous works of art. The contrast between the cold, stark colors of the ocean and the flashy neon of Rapture's buildings is the perfect testament to the designers' capability of creating interactive paintings. Accompanying the visuals, a an erudite soundtrack by Garry Schyman fills in the immersion gap, with moody piano ballads and claustrophobic cacophonies establishing the player's mood perfectly.
Usually, in my reviews of artistic games, every compliment has been said by the time I get to the game-play section, which is where I commonly start "bashing". Guess what? "Bioshock" is also grand on that regard. It takes the first person shooter / rpg hybrid mechanics of "System Shock 2", removes the unneeded complications, and empowers certain abilities, creating the perfect blend of open-ended first person shooter. The player has at his disposal a great number of weapons and abilities (which he can level up), each with a particular context of use, allowing the player to choose his particular fighting style. It's nothing that hasn't been done before, but in "Bioshock", everything feels tweaked and balanced, to the point of making complex mechanics inherently fun to use, while most games, either simplify them too much, thus discarding the tactical nature of choices ("Crysis"), or complicate them to the point of being too obtuse to be fun ("Deus Ex"). Furthermore, special abilities, which range from fireballs to electric shocks, have special uses when the environment's context is right, thanks to a physics engine that defines water as electric-conducting and oil as inflammable, making special abilities all the more amusing. Perhaps the only (minor) flaw I can find in this game (that can't be regarded as nitpicking) is the sometimes overly hectic nature of the action; for the most part of the game, there is someone (or something) trying to kill you. The reason this comes out as a flaw is simple: "Bioshock" is beautiful, immersive, and mysterious, warranting exploration and attention to detail in order to sink in all the wonders of the game, but it is hard to do so, when you're constantly fighting for your life. A more paced game-play would definitely emphasize the more interesting aspects of the game, even if it would end up losing some appeal for more trigger-happy players.
It's not hard to understand why someone who looks upon games as an art form, would love "Bioshock" in every possible way. It's one of the few games that actually wants, from the get go, to be regarded as much more than just a toy, or just a "game". Its aesthetics are beautiful, its message is strong, intelligent and emotionally provocative, and it is an entertaining game. It is, by my definition, the perfect example of a perfect game, and one of the best works of art I've seen in the past year.
